Thank You i got it right.
Solve the proportion using cross products. Round to the nearest hundredth if necessary.
3.7/2.4 = y/8.2
a) 10.56
b) 14.80
c) 12.64
d) 5.32

Answer 1

Answer:

c) 12.64

Step-by-step explanation:

$\frac{3.7}{2.4}=\frac{y}{8.2}$

$=\frac{y}{8.2}=\frac{3.7}{2.4}$

$\mathrm{Multiply\:both\:sides\:by\:}8.2$

$\frac{8.2y}{8.2}=\frac{3.7\cdot \:8.2}{2.4}$

$\frac{8.2y}{8.2} =y$

$\frac{3.7\cdot \:8.2}{2.4}$

$=\frac{30.34}{2.4}$

$=12.64166\dots$

Which is 12.64 in the nearest.
